Sorry, I am new to Mac so still understanding how everything works. Any suggestions or help is greatly appreciated.

Generally speaking...8gig of ram for most users really should be more than enough. So if you're not doing anything unusual or special...8gig of ram should be fine...and more ram may not be the solution.

Firstly...what sort of problems are you experiencing? If none...you may be "chasing your tail" trying to solve a problem that does not exist.

Maybe you can tell us what exactly you usually do on your computer...and what apps you generally have open at the same time.

Also...Mac OS 10.9 handles ram/memory differently than previous Mac OS versions...so those ram numbers you are seeing...may not be "telling the story" you think they are.

Finally...here are some article's discussing Mavericks & ram. They may be a bit technical...but maybe they will help:
